Hair lightening compositions and methods of use

Abstract

The present disclosure relates to hair care compositions such as hair treatment compositions and hair lightening compositions, methods for treating hair (e.g., lightening hair), and to kits comprising the compositions. The components of the hair treatment compositions may be included in hair lightening compositions and used to lighten and / or color hair. The hair treatment compositions typically include: (a) one or more polycarboxylic acids, and / or a salt thereof; (b) one or more amino acids, and / or a salt thereof; and optionally (c) one or more cationic conditioning agents. The hair lightening compositions further include (d) one or more bleaching agents.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 416,413, filed Nov. 2, 2016.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to compositions and methods for treating hair, kits comprising the compositions, and methods for using the compositions.BACKGROUND[0003]It is known that consumers desire to use cosmetic and care compositions that enhance the appearance of keratinous substrates such as hair, e.g., by changing the color, style, and / or shape of the hair, and / or by imparting various properties to hair, such as shine and conditioning. Many of the known compositions and processes for enhancing the appearance of the hair involve chemical treatment of the hair.[0004]The process of changing the color of hair, for example, can involve depositing an artificial color onto the hair which provides a different shade or color to the hair, and / or lifting the color of the hair, such as lightening the color of dark...

AI Technical Summary

Benefits of technology

[0011]Thus, one objective of the disclosure is to provide novel compositions that can provide advantageous effects such as strengthening of the hair fiber, protecting hair fibers from damage or further damage, enhanced properties such as softness, shine, conditioning, healthy appearance, while at the same time, providing desired effects such as coloring, lightening, straightening, relaxing, and / or shaping.

[0012]The present disclosure relates to compositions and methods for treating hair, in particular human hair of the head. The compositions and methods are unique because, in addition to lightening the hair, they dramatically improve the quality and durability of the lightened hair. Damage during chemical treatment (lightening / bleaching process) is minimized and / or compensated for due to the use of a treatment composition that may protects the keratin fibers of the hair.

[0013]The treatment compositions of the instant disclosure typically include (a) one or more polycarboxylic acids, and / or a salt thereof; (b) one or more amino acids, and / or a salt thereof; and optionally (c) one or more cationic conditioning agents. The treatment compositions may be separate compositions that are combined with one or more bleaching agents prior to use, or it can be part of a single hair lightening composition (a composition having one or more bleaching agents).

[0014]Useful polycarboxylic acids include, but are not limited to, dicarboxylic acids and / or tricarboxylic acids, a salt thereof, and a mixture thereof. Non-limiting of dicarboxylic acids include oxalic acid, malonic acid, malic acid, glutaric acid, citraconic acid, succinic acid, adipic acid, tartaric acid, fumaric acid, maleic acid, sebacic acid, azelaic acid, dodecanedioic acid, phthalic acid, isophthalic acid, terephthalic acid, and 2,6-naphthalene dicarboxylic acid, a salt thereof, and a mixture thereof. In some cases, particularly useful dicarboxylic acids include malonic acid and / or maleic acid, and / or salts thereof. Non-limiting examples of tricarboxylic acids include citric acid, isocitric acid, trimesic acid, aconitric acid (cis and / or trans), and propane-1,2,3-tricarboxylic acid, and salts thereof. In some cases, a particularly useful tricarboxylic acid is citric acid, and / or a salt thereof.

[0015]Useful amino acids include, but are not limited to, aliphatic amino acids such as glycine, alanine, valine, leucine, and isoleucine, and salts thereof. In some cases, glycine and / or a salt thereof is particularly useful.

[0016]Useful cationic conditioning agents, if present, include, but are not limited to, monoalkyl quaternary amines, dialkyl quaternary amines, and polyquaternium compounds.

Problems solved by technology

While dyeing or color lifting compositions can effectively alter the color of hair, and relaxing, straightening, perming, and waving compositions can effective alter the shape of the hair, these chemical treatments can damage the hair fibers and / or irritate the scalp.

However, the choice of components or combinations of ingredients could pose difficulties insofar as they cannot be detrimental to other cosmetic attributes such as ease and uniformity of application, rheology or viscosity properties and stability of the compositions, color deposit and target shade formation, and / or result into more disadvantages such as increased damage or a less healthy look to the hair.

These negatively charged moieties can degrade the cosmetic properties of the hair.
